This invention is an improvement in shade roller brackets of the type wherein the shade roller may be reversed in the bracket; and the primary object of the invention is to provide a bracket capable of receiving either the spade or spring end, or the pin end, of alshade roller, the holes in the'pair of brackets for receiving the spade or pin being so shapedas to maintain the roller 1evel,,or horizontally dis-posed, regardless of which end of the shade roller is placed'therein, whereby the shade roller maybe reversedin said brackets and; in either position, will be always disposed horizontally.

Another object of my invention is to provide a roller bracket of slot type,'pin type, or tension type having especially shaped spade or'pin receiving hole, as set forth above, and embodying convenient means for removing the roller for reversal thereof.

Other objects and advantages of my invention will become apparent during the following discussion of the drawings, wherein:

Figure 1 is a front elevational view of a conventional shade roller, mounted between a pair of my novel brackets of the pin type.

Fig. 2 is an end view of the assembly shown in Fig. 1, showing the spade or spring end of the shade roller supported in a bracket of the pin type.

Fig. 3 is an opposite end view of the assembly shown in Fig. 1 showing the pin end of the shade roller supported in the pin type bracket.

Fig. 4 is an end view of a modified form of the bracket, of the slot type.

Fig. 5 shows another modified form of bracket illustrating the tension or spring type.

Fig. 6 is a top view of the bracket shown in Fig. 5, taken along line 66 of Fig. 5.

Referring to Figs. 1, 2 and 3 of the drawings, the bracket l is of th pin-type, same having a flange la at its inner end, with holes lb therethrough adapted to receive mounting screws 2. The outer end lc of the bracket I is of substantiall semi-circular shape and a shade roller pin receiving hole ld is located at thte axis of curvature of said semi-circular end lc. The shade roller 3 has a pin 3a at one end, and a spade 312 at the other or spring end, the spade 32) being of the conventional spring operated type. Extending diametrically across the pin receiving hole ld is a vertically disposed spade receiving slot le, the respective centers of hole id and slot l e being coincident.

In the embodiment shown in Figs. 1, 2 and 3, a forwardly and upwardly extending inclined opening If in bracket I is provided, the Width of the 3 Claims. (Cl. 248-267) opening if being sufficient topass the pin 3a for removal or insertion of the roller p in the bracket. The lower wall Of opening l fie tangent to the lower periphery of hole ld while the upper wall is substantially parallel with the lower wall and converges at the upper portion of slot leproviding, a downwardly extending lip ix adjacent th upper end of slot'l'e at'the outer wall thereof. In this modification, the spade end 301 of the shade roller 3 would befirst inserted directly into the slot le in one bracket'l; and then the pin and 3a of said shade roller 3 could'be passed'diiectly through the slot if in the other bracket I so that thepin would seat in the related hole Id. Since the hole ld in both brackets iscentered co axially with the center of slot le, it is obvious,- that the spade end 3b could be entered into either of the brackets of said pair, and when the pin end 301 was seated in the other bracket the shade roller would be horizontally disposed.

Fig. 4 shows a similar bracket but with a, modified slot type inclined opening lg extending upwardly therein, said slot being wide enough to pass only the spade 3b and not the pin 3d. This form of the bracket has the advantage of holding the roller in tighter engagement with the pair of brackets, but has the disadvantage of making removal of the roller from the brackets more tedious. In this modification the lower wall of slot l g terminates adjacent the upper end of the hole ld rather than being tangent to the lower peripher thereof, while the upper Wall of slot lg terminates at the upper end of slot l e, so that a shoulder lh is left at the top of the slot le to prevent the roller 3 from jumping out of the bracket I if the shade end 3b is allowed to suddenly rewind unrestrainedly.

The tension type modification shown in Figs. 5 and 6 has no slot, such as l f or lg, communicating with the hole Id and slot le, but the bracket is made of resilient material so that it may be flexed as shown by dotted lines in Fig.6, from the pin 3a or spade 3b in the end of the shade roller 3 to permit removal or reversal thereof. The coaxial hole Id and slot le insures that the shade roller 3 will remain horizontal when supported in brackets l, regardless of which way the roller is supported in the brackets, since in reversible positions the center of the roller 3 is supported at the same height by the spade receiving slot le or pin receiving hole Id. It is important that the roller be mounted horizontally to insure even winding of the shade thereon, and to cause the shade to hang straight, particularly cular hole adjacent the outer end thereof for receiving said pin and having an elongated verti-1 cally disposed slot therein for receiving said spade; the center of the slot being coaxial with the center of said hole.

2. Brackets for reversibly supporting a conventional shade roller having mounting members including a pin at one end and a spring operated spade at the other end, each bracket comprising a plate; means for mounting said plate at its inner end to a support; said plate having a circular hole adjacentthe outer end thereof for receiving said pin, and having an elongated vertically disposed slot therein for receiving said spade, the center of the slot being coaxial with the center of said hole; an inclined slot in said plate for the passage of said mountin members into said vertical slot and hole, said inclined slot sloping upwardly from the outer corner of the top of said vertical slot, above said hole and providing a shoulder at the upper end of the vertical slot for preventing said mounting members from jumping out of said vertical slot, said inclined slot being of slightly larger width than said spade. v
